*Description*: This picture shows a comparison of images of the same region of the sky obtained with the Hubble Space Telescope Advanced Camera for Surveys (right) and the Subaru 8 meter telescope's Supreme camera. The region is an area from the GOODS North field. Both images are color composites obtained by combining three monochromatic images taken through blue, visible and infrared filters. The "seeing" of an astronomical object is a parameter that measures the sharpness of... Topics: Hubble Ultra Deep Field, HUDF, What -- Hubble Space Telescope (HST), What -- Advanced Camera for...

*Description*: Galaxies, galaxies everywhere - as far as NASA's Hubble Space Telescope can see. This view of nearly 10,000 galaxies is the deepest visible-light image of the cosmos. Called the Hubble Ultra Deep Field, this galaxy-studded view represents a "deep" core sample of the universe, cutting across billions of light-years. The snapshot includes galaxies of various ages, sizes, shapes, and colors. The smallest, reddest galaxies, about 100, may be among the most distant known,...
